Prose Captain

Prose Captain: an AI tool for creating, editing and optimising content that writes from a specific company's knowledge, using RAG and a Pinecone vector database.

For Prose Captain, we designed and built an AI content creation tool. At its heart is an editor where generating articles and posts goes hand in hand with editing them, while AI assistants work on clients' knowledge bases and optimise texts for search engines.

Challenge: AI without context writes in generalities

A language model without context writes in generalities. To be accurate, company content has to draw on the knowledge of a specific industry and company.

Prose Captain had to combine generation with editorial work: AI text is a starting point that needs to be easy to correct and adapt. On top of that, the content had to be search-friendly from the start.

AI was meant to speed up writing without sacrificing content quality.

Solution: a content editor with AI and company knowledge

The core of the product is an editor that combines AI capabilities with an interface for everyday work on text.

Articles, blog posts and other content formats are created in the editor. Generated text can be edited and adjusted straight away, in the same place.

Context from your own data

AI assistants work on client databases. With RAG and a Pinecone vector database, the language model receives pieces of a specific company's knowledge, so content fits its industry and needs. The system also optimises texts for SEO automatically.

Results: generation, editing and SEO in one place

Companies got a tool where generating, editing and optimising content happen in one place, based on their own knowledge.

Combining generation with easy editing is meant to shorten the time needed to prepare long-form content while keeping its quality, and SEO optimisation helps it reach audiences through search engines.
